A woman died after being shoved in front of an oncoming subway in the heart of Times Square Monday, and a woman arrested in the deadly shove may be linked to another subway death, police sources familiar with the investigation tell NBC 4 New York.

Police and firefighters swarmed the Times Square station at 42nd Street shortly after 1 p.m. after getting a report of a person pushed in front of a train. The 49-year-old victim was pronounced dead at the scene.

Subway deaths from pushes are not common, but there have been a few in the past few years. In 2014, Kevin Darden, 34, was charged with killing a 61-year-old immigrant from Hong Kong, Wai Kuen Kwok, by shoving him into the path of a subway train in the Bronx. He pleaded guilty to manslaughter and is awaiting sentencing.

In 2012, Erika Menendez, a mentally ill woman who had a history of attacking strangers, shoved an immigrant from India off a subway platform in Queens. She pleaded guilty to manslaughter and was sentenced to 24 years in prison. The victim, Sunando Sen, was 46.

Also in 2012, a homeless man, Naeem Davis, was arrested and charged with shoving Ki-Suck Han, a Korean immigrant, into the path of a subway train at a station near Times Square.

A fatal subway push in 1999 led to a state law, known as Kendra's Law, that allows supervision of certain patients outside of institutions to make sure they're taking medications and don't present a public safety threat. It came after the death of Kendra Webdale, who was pushed to her death by a former mental patient.
